  Looks like you may have a virus or other malware. Get your updated antivirus program and boot into Safe Mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan in Safe Mode. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

• Once implemented freezes screen, can get out of gel by Ctrl-alt-delete, starts in safe mode

  I had to do a full system recovery on my computer with Vista. Towards the end of installation screen is frozen on a blue screen which says that it was a single configuration screen and to ignore the messages etc. other than those who might ask you to restart.  This form has remained for more than 1 hour and a half before I dared to think that there might be frozen by pressing Ctrl-alt-delete and then cancel I could get the desktop to appear how I was responsible for approving some updates, more than 90 more.  Half of these updates failed, but future attempts had succeeded re installation. Now everytime I restart the computer, it goes back to the original blue single please wait screen.  I can go out with Ctrl-alt-delete. I also tried Microsoft Fix - It and the sfc/scannow not detected no problems. Any suggestions would be welcome.  Thank you.  Susan

  Hello

  Think about it an absolute must - manually update your drivers.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
  http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

  above is preferred so that the latest drivers from the manufacturer of system and device manufacturers are
  found)
  http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

  If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
  Updates, that leaves about Windows updates but it will not install the drivers that will be generally
  older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
  get new manually if you wish.

• Why don't I have to use Ctrl + Alt + Delete to use my computer?

  My PC starts directly from the windows 7 desktop.  How ever I can not click on the Start button.  If I open a desktop application I can't click any function on it once it is open.

  To have access to my PC, I have to Ctrl-Alt-Delete.  So I have to left click anywhere on the screen (not any text or button).  Then I can click on the Cancel button.  Once I did, I can use my programs as usual.  I have to do this every time I start my PC.  This problem exists from the outset, even though I have repeatedly re-installed Win 7 as a 32-bit and a 64 bit OS.  Since the first office sometimes.
  I have also not drag and drop functionality.  I can't drag my around my office desktop icons, for example in the trash.  This was not always the case and it takes place after the service of some or other update.  I spent this morning of uninstallation of updates as much as possible, until finally after a reboot, I could drag and drop from the desktop icons.
  A program that was unaffected by the problem of drag / move is iTunes.  I can drag tracks/albums from iTunes to a windows Explorer folder, but not a file Explorer windows to another.  I have to use the dialog box copy - paste on the right click of the mouse.
  What this problem is, it also affects Google Chrome by preventing the features left click on any of the control buttons.  By clicking a new tab, close...
  I'd appreciate a lot any input on that.
  My best regards,
  Duncan

  Hi Brian.

  It seems to me that you have disabled the Welcome screen at first upward.  You can check this by going to the "Start" menu and then go to 'Control Panel'.  Click on "User accounts" and then click on the option "Change the way users log on and outside."  You should now see two options.  The first is "Use welcome screen" and, with your current explanation, that has a checkbox that is empty.  Click the checkbox to enable the Welcome screen, then exit to the desktop, and then restart your machine.  After reboot, you should then see the Welcome screen with a list of all users. (If more than one.)  Sign in and then try Ctrl + Alt + Delete.  The task manager should now appear.

• Equium A100-549 - reading disc error occurred press ctrl + alt + delete to restart

  Hello

  I have a laptop Toshiba Equium a100-549, about 3 years, Windows XP Home Edition.
  Everything worked very well so far. When starting my computer, I received the message:

  A disk read error occurred press ctrl + alt + delete
  I don't want to lose my data

  Please please I need some advice what to do

  Kind regards
  AGM

  > I don't want to lose my data

  Well. Everyone knows that a HARD disk problem can happen and all of a sudden you may lose all the data stored on the HARD drive.
  That is why it s always recommended to backup the data on additional HDD, DVD, etc.

  I'm not sure if this will help but try this:
  Try to boot from the disk Win XP (NOT the Toshiba Recovery disk) and press r. means repair and should start the repair console.
  The similar DOS window should open and there, you can use a command:
  CHKDSK drive/p/r

  The chkdsk command checks the specified drive and repairs or recovers the drive if the drive requires it.

  More details can be found here:
  http://support.Microsoft.com/kb/314058

  If that does not help, then you need to reinstall new OS.

  HELP PLEASE! It is FUBAR or can the sick man computer repair - or better yet - can it be fixed at home with a few suport?

  Thank you!

  Hello

  To me, it seems that the HARD drive has developed a fault.
  Error message: error reading disk. Please press ctrl + alt + del to restart is a typical notification if something would be wrong with a HARD drive

  You can try to check the HARD disk using a disk HARD Drive Fitness Test.
  It s free tool google for it if you need details

  Run the test and check if the HARD drive is OK.
  No, then you will need a new HARD drive and you need to reinstall the operating system.

• No mode of the Tablet CTRL + ALT + DELETE key or Windows security?

  I just bought a laptop / Tablet HP TX2-1020US that came with Vista Home Premium.  Good so far.  I upgraded to OS to Vista Ultimate and my original SBS2008 domain-joined and worked on a large too.

  The problem is: when I'm in tablet mode, no button is "Windows Security" referred to in the prompt "press CTRL + ALT + DELETE or Windows security" in the starting System.  I end up having to convert portable mode, press CAD and convert again in tablet mode and use the biometric login each time.  Same thing to unlock the machine after an invocation of the screensaver, etc..

  HP support says they don't support "as sold" configuration, even if I am invited for an upgrade as it sets up for the first time, I am on my own if I do.  Not a very "the computer's personal again' approach to customer service... ;-)

  I thought I could reassign a touch on the surface of the Tablet--maybe the button "Mediasmart" I wouldn't need otherwise.  But the upgrade apparently took a toll on that too since the dialog box control Tablet PC Panel, in the general and the tabs button, I decidedly enigmatic after the upgrade and the tablet button ID is displayed as @BttnCmn.DLL,-2, -9, -7, etc. (for example the change in screen orientation button is @BttnCmn.DLL,-9).

  I would appreciate a solution that is running boards - the need to press CTRL + ALT + DELETE and brings me directly to where a slip of the finger is a login, or a reallocation of button so I could tap without having to disable-tablet-mode each time.

  Thanks in advance,
  Richard

  And one possible answer is:

  1. Administrative Tools | Local security policy
  2. (Elevation of privilege)
  3. Local policies | Security options
  4. Interactive logon to change: don't require CTRL + ALT + DELETE to "Undefined" to "Enabled".
  5. Close local security policy tool.

  CTRL + ALT + DELETE screen is bypassed, and the login screen is used instead (for which the fingerprint reader works fine).

  Thank you
  Richard

• CTRL + ALT + DELETE no longer works on my PC

  I used to be able to press CTRL + ALT + DELETE when my PC has pick up in a program. Now, when I do I get this: "Manager tasks has been disabled by the administrator."  My PC is being used and I don't know anything about a previous administrator.  How can I replace this message and return to the use of C + A + D? Or is there another trick to get out the programs that do not meet?

  What is your Version of XP and the Service Pack?

  Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

  If your system is at a standstill and you must use the Task Manager to kill a process, it is not normal and your system has a problem that you can solve.

  If your task manager has been disabled (unless you have disabled it on purpose), then you certainly have another problem to accompany your first problem.

  The usual advice along the lines of "something has been disabled in Group Policy" and that's probably true, but if you are using XP Home, is not Group Policy Editor in XP Home and which is not really you tell where to look in group policy, even if you run the Group Policy Editor.   You need to know how to fix it.

  Here is a complete solution that works for all versions of XP and requires no hunting around to find where things have been disabled in the Group Policy Editor.  If you happened to have documentation for Group Policy registry locations, there is no hunting, but most people don't have documentation.

  Unless you have disabled these tools on purpose, chances are good that your system has a malware infection.  The malware knows what tools you use to try to find and remove, for the malware disables the things you are more likely to consume and prevents them from running if you can't find it.

  All malicious software tools you currently use or have used failed to protect your system.

  The malware will be happy you trick into thinking that you need to so something drastic to fix your system - as a facility repair, system restore point or a total reinstallation of XP.  This is what it would be like you, but these measures are not necessary.

  You must solve the immediate problem of the tools does not, then scan your system for malware when you are finished.

  No matter what kind of malware you've used analytical tools, they are unlikely to solve this problem, because they cannot tell if the changes made to your system have been on purpose (you or an administrator who makes them) or some malware changed them, so the analysis tools will let these things alone (it's usually a good thing).

  If your task manager is afflicted in this way, there are probably other things that also do not work - like the registry editor, System Restore and the command prompt, so fix them all at once even if you have not discovered they are broken again.

  These commands from registry removes the registry entries that are stop opening programs.  Although the registry entries do not exist, these commands are safe to run.

  Before making any changes to your registry, back up the registry with this free and popular tool:

  Save the new text file with extension .reg on your desktop or somewhere you can remember with a name you can remember, something like:

  enableit.reg

  After you save the file, close Notepad.

  Locate the file enableit.reg on your desktop and double-click it.

  Alternatively, you can right-click on the enableit.reg file, choose open with... and select the registry editor.

  Answer in the affirmative to the question... Are you sure you want to add the information in the registry?

  You should then see a message that information has been registered in the register.

  If the registry editor has also been disabled, you will not be able to run registry changes to fix the rest of the problems, then you must first activate the command registry editor run.  Even if the registry editor is not broken, these commands are safe to run.

  Click Start, run and enter in the box (copy/paste would be safer) the following text:

  Tracking Add HKCU/v DisableRegistryTools /t REG_DWORD /d 0

  Click OK and answer Yes, if you are prompted with a message of crash.

  Click Start, run and enter in the box (copy/paste would be safer) the following text:

  Tracking Add HKLM/v DisableRegistryTools /t REG_DWORD /d 0

  Click OK and answer Yes, if you are prompted with a message of crash.

  Now that the registry editor has been enabled, you can run the enableit.reg file to troubleshoot issues.

  Depending on the circumstances, your tools can work right away, but go ahead to avoid the question "did you restart your system?" later, and restart your system at the time of trial to be sure things work again.

  Allow the tools in this way only solves the symptom of malware infection, but does not solve the real problem (the system is currently or has been infected by malware) so you're not quite done yet - your system might still be infected.

  Download, install, update and do a full scan with these free malware detection programs can solve any problems.

  They can be uninstalled later if you wish.

  You can also delete the enableit.reg file when you are finished.

  Do, or do not. There is no test.
